r7.01.45 Law of Behaviour RGI_BETON_BA

Summary:

The model presented in this document is an enhancement of a model already effective in Code_Aster: RGI_BETON (see R7.01.30). It makes it possible to consider reinforcements distributed within a concrete mass without differentiating their mesh. The behaviors of the two materials are evaluated and homogenized in order to deduce the response of the reinforced concrete material.
